“…In Europe, several parasitoids attacking the eggs of H. halys have been reported [23,[27][28][29], with Anastatus bifasciatus (Geoffroy) (Hymenoptera: Eupelmidae) being the most abundant native parasitoid among the few native egg parasitoid species; it is capable of developing on viable H. halys eggs [7,23,[30][31][32]. Thus, it is as a potential candidate for augmentative biological control in Europe [30].…”

Halyomorpha halys (Stål) (Hemiptera: Pentatomidae) is an endemic species of East Asia; it was introduced into Europe in 2007. It has a wide range of hosts as it feeds on over 170 host plant species and significantly impacts crop production. In Greece, H. halys causes significant losses in the production of kiwi, peaches, and green beans; thus, control of this species (including biological control) is essential. Here, we focus on the potential impact of native natural enemies of H. halys in Greece. From June to October 2020, we sampled naturally field-laid H. halys egg masses to recover native parasitoids. A total of 20 egg masses of H. halys were collected from infested fields from different locations in northern Greece. Out of 529 eggs, 45 parasitoids managed to hatch successfully. The overall parasitism rate was 8.5%. We found two species of Hymenopteran egg parasitoids attacking H. halys eggs—Anastatus bifasciatus (Geoffrey) (Hymenoptera: Eupelmidae) and Ooencyrtus telenomicida (Vassiliev) (Hymenoptera: Encyrtidae), with the former comprising 58% of all parasitoids that were recovered. These results contribute to the knowledge about the natural enemy community that attacks H. halys in Greece, and the use of these native egg parasitoids in biological control programs may be a viable H. halys management strategy.

“…For instance, higher parasitization of H. halys by T. mitsukurii was detected in naturally-laid eggs compared to sentinel eggs (Zapponi et al 2020). In other two studies, T. mitsukurii exhibited remarkable discovery e ciency of naturally laid eggs on plant tissues, with 27.3 to 46.5 % of parasitised egg masses (Scaccini et al 2020;Bout et al 2021).…”

“…Induced plant volatiles act on long-distance range and are easily detected by the egg parasitoids, allowing them to rapidly locate the host that is suitable only for a short period of time (Vet and Dicke 1992;Colazza et al 2004). The ability of T. mitsukurii to exploit oviposition-induced plant volatiles for locating H. halys, although it is investigated here for the rst time, was recently hypothesized following results of open eld surveys in northeast Italy or France (Zapponi et al 2020;Bout et al 2021). For instance, higher parasitization of H. halys by T. mitsukurii was detected in naturally-laid eggs compared to sentinel eggs (Zapponi et al 2020).…”

“…In Italy, adventive populations of T. mitsukurii have shown high parasitism e cacy on H. halys, comparable to that of T. japonicus (Scaccini et al 2020). This considering, T. mitsukurii is reckoned as a promising egg parasitoid of H. halys in Italy and neighbouring countries (Bout et al 2021;Rot et al 2021), and is currently under evaluation for the development of a pre-emptive biological control program of the stink bug in Australia and New Zealand (Caron et al 2021).…”

Field release of classical biocontrol agents requires prior risk assessment to ensure that non-target effects are averted. No-choice and choice bioassays can provide basic information on the physiological host range of the candidate agent. However, other experimental methods, like olfactometer bioassays of host-plant complexes, can depict more realistically the likelihood that the released biocontrol agent localizes non-targets in the field. Halyomorpha halys Stål (Hemiptera: Pentatomidae) is native to Asia and invasive in North America and Europe, where it represents a major threat for crops. The Asiatic egg parasitoid Trissolcus mitsukurii (Ashmead) is adventive in Italy and exhibits high parasitization ability on H. halys. In the light of evaluating T. mitsukurii for H. halys biocontrol, its physiological host range has been already partially explored. Here, we investigated the ability of the parasitoid to exploit odours associated with H. halys or with the following non-targets: Arma custos F., Dolycoris baccarum L., Eurydema ventralis Kolenati, and Nezara viridula L. (all Hemiptera: Pentatomidae). Specifically, using a Y-tube olfactometer, we tested the response of parasitoid females to plants bearing naturally laid eggs, to physogastric females or eggs of the different species. We observed that T. mitsukurii is only attracted by plants challenged by eggs of H. halys or N. viridula, while it is not attracted by physogastric females or eggs alone. Remarkably, T. mitsukurii was almost repelled by plants bearing eggs of the beneficial A. custos. Our results usefully contribute to a more valuable assessment of the potential non-target risks in case of parasitoid release.

“…Meanwhile, adventive populations of T. japonicus have been detected in Switzerland and in Italy in 2017 and in 2018, respectively (Sabbatini-Peverieri et al 2018;Stahl et al 2019c;Moraglio et al 2020). Furthermore, also adventive populations of Trissolcus mitsukurii (Ashmead) (Hymenoptera: Scelionidae), another Asian parasitoid of H. halys eggs in Japan (Arakawa and Namura 2002;Kamiyama et al 2022), have been found in Europe, in Italy and in France in 2016 and 2021, respectively (Scaccini et al 2020;Bout et al 2021). This species has been considered as another promising candidate for biological control (Sabbatini-Peverieri et al 2020;Caron et al2021;Giovannini et al 2022).…”

No adverse effects of symbiotic control on the parasitism of Halyomorpha halys by egg parasitoids

The brown marmorated stink bug Halyomorpha halys is a polyphagous insect, which has a devastating impact on agricultural production in many countries. The alteration of symbiont vertical transmission, by removing symbionts from stink bug eggs (symbiotic control), has been recently introduced in control programmes against this insect. A major advantage of this strategy is the compatibility with natural enemies, since it allows an insecticide-free approach that is not harmful to other agroecosystem components. However, the effect of anti-symbiont products on parasitism by egg parasitoids is still unexplored. Here, we investigated the impact on parasitism by native (Anastatus bifasciatus, Ooencyrtus telenomicida and Trissolcus kozlovi) and exotic (Trissolcus japonicus and Trissolcus mitsukurii) parasitoids that attack H. halys eggs, after treatment with the micronutrient biocomplex Dentamet®, used for symbiotic control. The native wasp species were tested in no-choice bioassays, showing that treatment of the egg masses did not affect emergence percentages, but the non-reproductive effects were often reduced by the biocomplex. The exotic species T. japonicus and T. mitsukurii were used in no-choice and paired choice bioassays, showing an opposite influence of Dentamet® on emergence percentage and preference in the two species. No-choice tests indicated the highest successful parasitoid emergence on biocomplex-treated egg masses for T. japonicus, while no preference in the paired comparison with eggs treated with water or untreated. In contrast, T. mitsukurii displayed the lowest parasitism after Dentamet® treatment in no-choice tests, and preferred egg masses without Dentamet® in paired choice tests. We did not record any natural symbiont acquisition by the parasitoids emerged from H. halys egg masses, indicating that the wasp fitness is very unlikely to be altered by dysbiotic effects resulting from treatments. Therefore, our results support a further implementation of symbiotic control in different crops in combination with biological control, as sustainable options for H. halys integrated pest management.
